should therefore have been such slaughter as at Drogheda and at Wexford is nothing surprising,[177] however deplorable. What is really remarkable in such a war is that Cromwell, from the moment of landing, should have paid his way, visited plunder with the sharpest penalties, and upheld the sternest and most inflexible discipline. Forty years later, when the conquest of Ireland was undertaken by a former marshal of France and a king long schooled in war against the first generals of the time, they were glad to search out Cromwell's plans for his Irish campaign and follow them at such a distance as they might. [Sidenote: 1650, January 8.] [Sidenote: June 12.] [Sidenote: June 26.] Cromwell was still in full career of victory when the alarming news of a treaty between Charles the Second and the Scots moved the Parliament to recall him to watch over its own safety. He arrived in London on the 1st of June, and was joyfully welcomed not only by Fairfax and the officers of the Army but by all ranks and all classes. It was now almost certain that the Scots would invade England in the King's name, and no time was lost by the Council of State in appointing Fairfax and Cromwell to command the English army in the north. That they would work loyally together in the field no one could doubt; but when the Council consulted the two generals as to plan of campaign, their opinions were found to be diametrically opposed to each other. Cromwell was for taking the bull by the horns and carrying the war into Scotland before the Scots could cross the border; Fairfax, never quite at his ease since the establishment of the Commonwealth, thought such aggressive action unjustifiable. It is impossible to believe that this was his true military opinion, but not all the arguments of the Council nor the pressing entreaty of Cromwell could prevail with him to alter it. Despite all protests he resigned his commission on the plea of physical infirmity, and from this moment passes out of the history of the Army. Never perhaps has that Army possessed a more popular and deservedly popular commander-in-chief.
